I got the full Akra system and my advice is that when you put the plastics back on, make sure that none of the pipes are touching the plastics....
I put mine on and there was a scent which I thought was the baffle just burning but what it turned out to be was that part of the header pipe was touching my lower fairing on the left side where there is a cut out and melt part of it off......
Also, its hard to reach the oil filter with an oil wrench...
Other than that, I'm happy with the performance and sound....
